Once installed ntp package run on your system,
Starting ntpd: [ OK ]

udp 0 0 220.127.116.11:123 0.0.0.0:*
udp 0 0 127.0.0.1:123 0.0.0.0:*
udp 0 0 0.0.0.0:123 0.0.0.0:*
udp 0 0 fe80::216:3eff:fe97:232c:123 :::*
udp 0 0 ::1:123 :::*
udp 0 0 :::123 :::*
Do you want to set clock time on boot time, Open a rc.local file and add a line into it.
Once updated on that file the system clocks will be changed on next boot.
